The correct answer is: B. MIT
The original LISP machines produced by both LMI and Symbolics were based on research performed at MIT. In the early 1960s, John McCarthy, a computer scientist at MIT, developed the Lisp programming language. Lisp is a functional programming language that is well-suited for artificial intelligence applications. In the late 1960s, McCarthy and his colleagues at MIT developed the first Lisp machine, the LMI Lambda 600. The Lambda 600 was a commercial failure, but it laid the foundation for the development of later Lisp machines.
In the early 1970s, a group of researchers at MIT founded the Symbolics Corporation. Symbolics developed the Lisp machine that became the standard for AI research in the 1980s and 1990s. The Symbolics Lisp machine was based on the research of McCarthy and his colleagues at MIT.
